OpenVPN server performance

vv

Hi,
I want to host OpenVPN server to which 1000 VPN clients should be able to connect simultaneously. What should be the configuration I can use.

And I tried hosting OpenVPN Server with 10.11.2.0 255.255.255.0 , with this only 60 clients were able to connect. I saw the ipp.txt, which showed the IPs assigned to clients like (10.11.2.4,10.11.2.8,10.11.2.12...) in the increments of 4. I am not sure why this happening

Regards,
VV

Please read the manual about assigning IPs to clients: http://openvpn.net/index.php/open-source/faq/77-server/273-qifconfig-poolq-option-use-a-30-subnet-4-private-ip-addresses-per-client-when-used-in-tun-mode.html

Thanks. It was really helpful. I can understand that the IPs are assigned in increments of 4 in windows OS but is that same for Linux OS also.

Instead of 10.11.2.0 255.255.255.0 do this,

#Client DHCP pool
ifconfig-pool 10.11.2.0 10.11.5.255
#Server IP
ifconfig 10.11.1.1 10.11.1.2
#Client Route
route 10.11.0.0 255.255.0.0
push "route 10.11.1.1"

Or use whatever address you are comfortable with.
